Optical Properties and Thermal Geometries of Hot NUT-Kerr-Newman-Kasuya-AdS Spacetime
This paper is devoted to studying the optical and thermal geometrical
properties of Hot, NUT-KerrNewman-Kasuya-AdS black hole (BH). This BH is
characterized by the NUT charge and a parameter Q that comprises the electric
and magnetic charge. We compute the image of the BH shadow in two types: 1) at
infinity, 2) at specific limit by analytical approach. We also investigate the
effect of Nut, spin, inclination angle, and cosmological constant on the shape
of shadow. We analyze that for type 1, the shadow in increasing for higher
values of NUT charge, the cosmological constant, rotation parameters, and
inclination angle, while for type 2, by increasing these parameters, the
circular symmetry of the image of the BH shadow variate. Moreover, we discuss
well-known thermal geometries such as Weinhold, Ruppeiner, HPEM, and Quevedo
case I & II spacetime. It is found that Ruppeiner , HPEM and Quevedo (II)
formulations provide physical information about the microscopic structure as
compared to Weinhold and Quevedo (I) geometries of Hot
NUT-Kerr-Newman-Kasuya-AdS BH. Our findings provides distinctive
characteristics in the shadow and thermal geometries of this BH as compare to
other BH types.
